Ye could also request the original files and I'm sure some floof happens to 'ave what ye need.
As for the missing markings in-game, ye'd possibly need to track down that extra FH and delete it. Although, I'm not sure why 'tis doing this, 'cause I happen to 'ave an extra FH on m'computer for the sake of the original files-which I'd be happy to give ye, if ye want them-and I do not 'ave this glitch. {I'm out atm, so ye'd 'ave to excuse the wait.}
What ye could also do is before ye delete the copy, is to salvage the original textures that ye need.
